In 1959, physicist Richard Feynman presented an
amazing talk entitled There's Plenty of Room at the Bottom, in which he proposed making very small circuits out of molecules. More than forty years later, people are starting to realize his vision. Thanks to Scanning Tunneling Microscope (STM) probes and "self-assembly" fabrication techniques, it is now possible to connect electrodes to a molecule and measure its conductance. In 2004, Mark Hersam et al. reported the first experimental measurement of a molecular resonant tunneling device on silicon. This new field of Molecular
Electronics may someday provide the means to miniaturize circuits beyond the limits of silicon, keeping Moore's Law in force for many years to come.

Notes on the Ballistic MOSFET
08 Oct 2005 | Papers | Contributor(s): Mark Lundstrom
When analyzing semiconductor devices, the traditional approach is to assume that carriers scatter
frequently from ionized impurities, phonons, surface roughness, etc. so that the average...
Field Regulation of Single Molecule Conductivity by a Charged Atom
29 Jul 2005 | Online Presentations | Contributor(s): Robert Wolkow
A new concept for a single molecule transistor is demonstrated. A single chargeable atom adjacent to a molecule shifts molecular energy levels into alignment with electrode levels, thereby gating...
An Electrical Engineering Perspective on Molecular Electronics
26 Oct 2005 | Online Presentations | Contributor(s): Mark Lundstrom
After forty years of advances in integrated circuit technology, microelectronics is undergoing a transformation to nanoelectronics. Modern day MOSFETs now have channel lengths that are less than...
Simple Theory of the Ballistic MOSFET
11 Oct 2005 | Online Presentations | Contributor(s): Mark Lundstrom
Silicon nanoelectronics has become silicon nanoelectronics, but we
still analyze, design, and think about MOSFETs in more or less in the
same way that we did 30 years ago. In this talk, I...

DNA Charge Motion: Regimes and Behaviors
28 Jul 2005 | Online Presentations | Contributor(s): Mark A. Ratner
Because DNA is a quasi-one-dimensional species, and
because each base is a pi-type chromphore, it was long ago suggested that DNA could conduct electricity. This has become a widely...
